Aquara multisensor - connected but with lqi 0/0

Hey there,

i have an aquaria multi temperature-sensor. It suddenly stopped sending values and so I looked at the decoz-gui.

There I see that is connected (green line) but with lqi 0/0.

Does anyone of you know how to fix this?

Perhaps this helps

hmmm. now the green line without lqi isn’t there anymore.

But now there is no connection at all to the sensor. I tried to repair the sensor several times but it does still get no connection ;-(
